KIRK KELLOGG, OF KALAMAZOO, MICHIGAN.

PLOW.

SPECIFICATION forming part of Letters Patent No. 264,885, dated September 26, 1882. Application sied .my 1,` 1882. (No model.)

To all whom it may concern:

Be it known that I, KIRK KELLoGG, a citizen of the United States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented new and useful Improvements in Plows, of which thefollowing is a specification.

My invention consists in an improved construction for blind-boiting the detachable parts of a plow with the shoe or support.

In the drawings forming a part of this specification, Figure 1 is a side elevation partly in perspective, showing by dotted squares the lo-l cation of bolt-heads in the exterior surface of the mold-board of former plows 5 Fig. 2, a plow with mold-board removed; Fig. 3, inner surface of mold-hoard, and Fig. 4 a section on line l l in Fig. 1.

On the inner surface of the detachable parts (see mold-hoard D for an illustration) I form; ribs a a, having a channel between them, the sides of which channel form oblique angles converging froin their hase. P is the detachable point, and r the detachable landside.

-In shoe B, at proper locations for the connections of parts, are formed countersinks e e,

Vwhich are perforated through the center and adapted to receive the ribs, constituting a boltl more liable to clog by the dirt collecting by the .bolt-heads.

As the bolt-heads F are movably located in the recess, which is made hon ger than said heads, the bolt can be readily centered in the hole in the center of the countersink by slipping the bolt-head in either direction, and

hence the frequent variation'in the-shrinkage y.

of the cast pants does not interfere with their speedy connection. Should this variation he Vso great as to bring` the recessed ribs a a out of a proper location to easily enter the countersinks, said rib can be readily ground ofi' a little, in lieu of grinding the castings themselves, which frequently ruins -them without veffecting the desired result.

The object, of course, of locating the bolthead recesses in the countersinks is to keep the part connected with the shoe from slipping, which it would otherwise do, owing to the capacity. of the bolt-head to move in said recess.

Having thus described my invention, what I' l. The shoe ot' a plow having the perforated countersink, in combination with a detachable part ot' the share having the bolt-head recess, and the bolt having a` head'adapted to fit adjustably in said recess, all substantially as set forth.

2. A detachable part of a plowshare provided withthe bolt-head recess, the shoe having the perforated countersink, and the bolt having a securing-nut and a head adapted as set forth, substantially as shown.

KIRK KELLOGG.
